This particular example sports a single barrel heavy cannon. Additional weapons systems are added to act as close-up infantry/vehicle suppression. The turret on the top is a twin-barrel heavy machine gun. (This turret actually rotates a full 360 degrees.) Two smaller machine guns are mounted in weapons pods just below the viewing ports on either side of the main turret.
Crew access is via the double-door hatch at the rear of the main turret, although there also is a small hatch located on top of the upper turret. This gun stands about 3-3/4 inches (95 mm) tall. The base is 4-3/4 inches (120 mm) in diameter.
